Elder Care in Pennsylvania: Do You Know the Symptoms of Lewy Body Dementia?

Lewy body dementia (also knowns as dementia with Lewy bodies) is the third leading cause of dementia in the United States, and is often misdiagnosed as Parkinson’s disease or Alzheimer’s due to the similarities in their presentation.

Lewy body dementia is caused by the presence of Lewy bodies in the brain. These protein deposits can lead to serious problems in thinking and reasoning, even if scientists do not know exactly why they form. Their name comes from Dr. Frederick Lewy, who discovered them in the early twentieth century when he was working alongside Dr. Alois Alzheimer, for which Alzheimer’s disease is named. Lewy discovered that the protein in Lewy bodies is prevalent in the brain, but as of yet, no one has been able to figure out what it does for the body when it is working correctly.

As you can see, there is a lot of mystery surrounding Lewy bodies and the dementia they cause, but there are, however, some telltale symptoms of the disease that you or your elder care might notice in your aging parent or loved one.

Here is a list of the most common signs and symptoms to keep an eye out for:

  • Confusion – Does your loved one seem to be having difficulty concentration or comprehending what is happening around them? This lack or alertness usually varies from one time of day to another (for example, your loved one might be more alert in the morning, but very confused and disoriented around lunchtime), or from day to day. It is not usually consistent, which can make it even more stressful for the person suffering from it.
  • Memory loss – Loss of memory might seem like a symptom of Alzheimer’s, but it is a symptom of Lewy body dementia as well. In this case, memory less is usually less extreme, but it is still significant. If you or your elder care aide notice that your senior is having trouble remembering names or faces or things that they knew yesterday, it is important to get this checked out by a doctor.
  • Hallucinations and delusions – Perhaps one of the scariest symptoms of Lewy body dementia is the presence of visual hallucinations. The sufferer sees things that aren’t there, and might not realize that what they are seeing isn’t real. They might also have delusions, and think things are happening when they are not, which can be tough for the people around them, if they don’t understand what is going on.
  • Parkinson’s symptoms – There is a reason that Lewy body dementia is often mistaken for Parkinson’s and vice versa. They have many of the same symptoms, including hunched posture, trouble maintaining one’s balance, and tremors or stiffness in the muscles.


If you or your elder care aide suspect that your aging parent or loved one might be suffering from Lewy body dementia, schedule a doctor’s appointment as soon as possible. This disease is not curable, but it is possible to manage it in some ways, and make life more comfortable for the person who is experiencing it.
